citizen of thellnited. States, 'and a resident- O Great Lakes,y NorthChicago, in the county of lLake" and ,State of vIllinois, 'formerly ofthin city Ioi New York, borough of Queens, in the county oi Queens andState of New Yo1k,h'a've invented a new and Improved rl`orpedo-'SteeringBIechanisin, of which theii'olloiving is `a full,l clear, and

Among the principal objects which the present invention. has in vieware: to pro- Ivide mennsfor maintaining a. torpedo on a relativelystraight course; to provide van Ioperating mechanism lor a steering gearto eiect the above-mentioned purposes easily and positively, and toprovide operating means for the steering rudder, said .means beingremovable from service position without loss of tim(` and without undueeliort.

' One embodiment of the present invention -is shown in the accompanyingdrawings, in

Whichv Figure 1 is a sectional elevation of the rear end fragment of atorpedo, operating partstherefor, and a steering gear connectedtherewith constructed and arranged in accordance with thepresentinventiom'Fig. 2 is a top plan view of an automatic mechanism forcontrolling the torpedo steering mechanism; Fig. 3 is a sectionalelevation of the same: Fig. e'lis a detail view showing the automaticmechanism for controlling the steering mechanism in operative position.

As seen in the drawings, the torpedo body 9 is provided with an openingto receive the hody section 10, from which a lin section 11 is extendedin line With a tail lin 12 of the torpedo.

The body section 10 is enlarged substantially as shown in'Fig. 1 of thedrawings, to forni i level table 13,'on which is mounted standards 14 tosupport guide rails 1,5. he guide rails 15 are best seen in Fig. 2 ofthe drawings. Said rails are grooved along the edges of each to supporta carrier 16. The carrier 16 is rapidly reciprocated longitudinallyhetvveen the rails 15, yvhich movement is utilized to Y:meinte as aconstant corrective or control fo` the main vertical steering rudders17.

The rudders 17 have a plurality of blades,

leach connected by means of ashort post 18 with a yoke 19 disposedWithin the tail casing 2O of the torpedo, and there connected with avpiston rod 21. The piston rod 21 is provided with a piston 22,'Which isreciprocatively mounted in ,a cylinder 23, t0 which compressed air, gasor steam is admitted ,by means of port passages 24.

The passages 24 are opened or closed by a valve 25, which valve isprovided with a valve rod 26, the opposite lend of which is pivot-allyconnected to a bell crank lever l27.

The hell crank lever 217 is pivotally mounted by means of a pin-28`on(fine of the rails 15.

The bell crank lever 27 is rocked on its pivot by 'the Acarrier 16 when,a blade 29'is moved in the path of either oi thearms 30 or 31. The arm31 is rigidly connected with the bell crank lever 27. T he arm 30' is aportion of a bell crank lever 32 which is pivotally mounted on the rail15 opposite that supporting the bell crank lever 27. rIlle bell cranklever 32' is connected to the hell crank lever 27 hy means of a link rod33, all as shown in Fig. 2 of the drawings.

From the construction it will he seen that as the blade 29 is brought inContact With one or the other of the arms 30 or 31, the valve rod 26 andvalve 25 connected therewith are moved to the left or rightrespectively, to expose the port at the right of the cylinder 23 toreceive pressure from a chest 34, While the port at the lefto saidcylinder is opened to exhaust through a port 35. The engagement by theblade 29 of the arms 30 and 31 is dependent on the swing of acourse-correcting plane 361Which is supported in bearings in the iinsection 11 to lie normally flush therewith,'whichposition itwill assumewhen the Water pressure on Asaid plane is equal atfopposite sidesthereof. Vhenever, 1n the operation of the torpedo, the Water pressureon one side becomes greater than on the other, the plane 36, yieldingthereto, turns upon its pivot, together with the post '37 and the head38 mounted thereon. The head38 isextended toward the path of the carrier16. The end of the head is shaped topa-ss between the fingers 39 and 40of a rocking plate 41 when said plate is in position so. that the blade29 passes between t e endsof the arms 30 and 31.

Then for any reason-the lane 36de delected relative to the axis o thetorpedo-1Qv generally causedy by the torpedo swinging from itsinitialcoursethe head 38 is rotated to engage one of the fingers 39 or 40,which rocks the plate 41 in such manner as to cause the blade 29 toengage one of the,

tion, or moves the same in relation to the body of the torpedo to theleft thereof. This Y movement of the plane 36 to. theleft operates thevalve mechanism of the cylinder 23, to move the piston 22 therein todeflect the rudders 17 vto the right of the body of the torpedo,operating asa corrective to bring the nose of the torpedo up into-theinitial course.

' As the torpedorights its position, the plane 36 swings relatively to aplane iush with the tin section 11, or parallel to the longitudinal axisofthe torpedo. If, in swinging in answer to the impulse given by .therudder 17, the torpedo now pays oi to the right, the sure of the wateron the left side o the plane 36 holding the same'yn the manner abovedescribed, rotates the same relatively to the right of the new positionof the torpedo, when the head 38 swings into the path of the oppositefinger 39 or 40 tfrotate the slxzt-fbeing relatively small.

plate 41 so that the blade 29 interferes with the opposite arm 30 or 31,as the case may be, and reverses the rock 'of the lever 27V andtheoperative position-.of the valve 25 connested therewith', `to the endthat the piston 2.2 is moved to throw the rudders 17 to the left of theaxis of the torpedo, swinging the nose again to the initial course.

The operation above described is dependent on the reciprocation of thecarrier 16. To this end the carrier 16 is furnished with a standing pin42 which extends into a cam slot 43 formed in a collar 44 which ismounted on the driving shaft 45 of the torpedo. lThe slot 43 is inclinedto the vertical sulficiently to move the pin 42 and carrier 16 and plate.connected 'therewith so that the ingz-irs89fand 4 0 thereof pass theadl vi edied'ge of the head 3S.
